Was the methanol run through the DI system? -- I have developed the idea that a portion of the fuel is converting to gas phase on PFI which means it's less dense, which means there's less air to react. -- That said, on an endurance application, I prefer to keep PFI because it keeps the intake ports clean. -- The 70hp difference computes to 10%. I wonder how much of that is evaporation from the hot intake valve, and how much of that is ledenfrost off the piston and cylinder. The way wet flow goes through the LT1 might have a defined effect in all of this, and careful consideration of tradeoffs seems appropriate.

Very interesting video, and I appreciate your sharing this. But as I was watching, I immediately thought the numbers didn't check out. You reported a 7.3% loss of airflow due to fuel displacing air in the port in the port injected engine. But fuel does not take up 7.3% of the air going into the engine; by my math, the fuel volume going into the engine is just 0.0144% of the air volume assuming a 12:1 AFR. Am I missing something, or did I do my math wrong? If my math is right, then fuel in the port displaces a negligible volume of air, and your conclusion is totally wrong, the airflow and power gains coming from a totally different mechanism. I don't think you're wrong, it's much more likely that I am wrong. But the math just doesn't check out. I want to understand this better. Help! My math says that it is only possible for the gasoline to displace 7.3% of air if you were running an AFR of 0.023:1, or 42x more fuel than air(by mass).

Kinda cool. At 2:30 they were talking about an airflow change of about 7%. Stoichiometric efficiency is 14.7:1. Well, 1÷14.7= .068...about 7%! The fuel volume is reflected in their flow numbers!😮

Why on earth would you use a gen 5 head on a gen 4 block just to block the injector port off? This makes no sense at all, as gen 5 heads have smaller ports designed for air only flow.

How would this cam do in a 6.2 ss

What exhaust yall running? Im looking for that Metallic resonance your sporting. And that chop... shooo,weee

Does the truck norris nsr cam have a good lope to it ,and what would be a good cam for a Z71 4x4 2010 5.3, everyday driver with good performance and lope

Yeah, it makes more TQ because you listen to DV and built a whole cam around it

What cam Is this ?

What a great video! Thanks Brian!

5.3 6.0 6.2?

looking forward to talking to you guys soon, I have a couple hemi swaps coming into a 79 Ramcharger. Haven't decided on 5.7 or 6.4 in either case yet. Later a 72 Duster may also get one.

This cam vs the red hot cam for a 404 ci? With ls3 heads?

Whats the engine setup?

Nitros threw the original fuel injection port????? Just a thought direct injection nitros

Are the knocking off the packaging now? See the stuff all over Amazon now

Is this based on Smokey's old smoketron?

Stock lifters ?

Looked like fun guys! Can't wait for it at LSFest EAST!

Thanks to Matt Brown for knowledge on the L8T cam options, and the quick follow up by e-mail.

Who tuned it

What duration

Is should have made a trip out..

It was a blast! Definitely gonna come back next year for a trophy 🤘

Good Video & Tech.

Thanks for having us!

the tuner doing the lords work sellin bibles door to door....patiently massaging the e92 into submission on a phase limited gen v with a healthy dose of TEL aka "lt4 lithium" like a scene from pulp fiction when jules quotes Ezekiel 25:17......you will know my name is the LORD as the rollers spin 835 at 7125 👏

Awesome video guys!

I'd like to see you guys check out the Southern Illinois Truck Showdown. This will be the 3rd annual event. Anticipating 1000 trucks this year. I will be representing you guys with my Truck Norris cammed LQ4 6.0 😊 As always, thank you guys for doing what you do for all of us!

Man you skipped so many steps explaining to someone who is learning this.

Thank You, BTR...

My dad has a 2015 Z/28 🔥 black on black 427 under the hood 505 horse... 6 speed manual. Im in Canada gets put away every year never seen snow or rain only has 22.000km on it.

Honest question, why do some videos of machinists use fluid and some don’t? I would’ve thought any machining would’ve required some sort of coolant?

Thanks , This The Great Car Video / Channel & Good Work ! Hello From Finland & My Car Channel ! #Retired4You All The Best to You 2024 !

This is a ls3? What type of rocker arms and pushrods?

Welp good thing I had a delphi lifter and tray upgrade when my engine was rebuilt. I wouldn't be surprised if they were BTR products considering my cam is BTR as well. On a side note: The BTR Stage 1 220 cam apparently can handle more than 7000 rpm's. Currently having my trans tuned and *cough* couple of times hit 7500-7600 rpms. Still working the kinks on the tune as we speak.

Nice. Got to get me a set of these as soon as I swap out my 4.3 v6 with a LS

Lt1 the same as 5.3 /6.2 heads ?

I would like to know what you think about Elgin Industries lifters, ive used them in daily abused LS swapped cars, using your cams, and never had a lifter fail. Since atleast 2016!!! I have Ls swapped over 40 cars, Trucks, and Jeeps using them.

Why does this matter.? What benefits u getting?

Guess its a good thing I have a Stage 1 Gen V BTR 220 cam with VVT limiter in my car.

Go eagles!

I had Carter for a teacher in Highschool. I remember I signed up for automotive my freshman year but got put into Agriculture because the Auto teacher was retiring after that year. Carter was a substitute that year and I really liked him as a Sub. He wound up becoming the Auto Teacher full time my sophmore year, I took his classes in my junior and senior years and they were by far my favorite classes. I actually bought his daughters old truck from him while I was in his class. It was a 02 Dodge Dakota, blue, extended cab, 4wd drive, 4.7l that he had rebuilt the motor in. I remember another kid in the class with an old Single cab obs with a 350 wanting to race and Carter told him he didn't stand a chance😂 He was my second favorite teacher of all time, and if he sees this he was a very close second to Mr.Karnes and I'm sure he'll understand😂

My home town!!!! This group is amazing for our kids

You're smart but wrong

I'd never go anywhere but BTR direct

@crystalhooks in the chevy luv!

That's an interesting Chevy LUV, '74-'76. Lotta motor, little weight.

Great video! Thanks for sharing!

It was a great event with top shelf racing parts. BTR for the win!!
